Abstract: A lens drive device includes a holder that holds a lens for shake correction from an outer peripheral side of the lens, and a plurality of coil motors that are disposed along a circumferential direction of the lens with respect to the holder. Each of the coil motors includes a magnet, a yoke that forms magnetic flux along with the magnet, and a coil that has an air-core portion. The coil is fixed to the holder. The yoke is inserted into the air-core portion. The coil is configured to move the holder in a lens radial direction by generating thrust from an applied current and magnetic flux. The yoke has a dent where a side surface in the yoke facing an outer peripheral surface of the lens is formed in a shape recessed in a direction of being separated from an optical axis of the lens.
